    Strengths:    smooth, fast, silent

    Weaknesses:    light action can be tricky on friction setting (and who cares?)
    hardly cheap

    Bottom Line:   
    upgrading froma 105 rear mech is a big step, but I have been amazed how much difference. i've been able to drop two sprockets at the rear, going froma 13-23 to a 12-21 block. With a 9 sp ultegra block and chain the ride is absolutely silent, shicting light and accurate, witht the only proviso that tehre seems to be a slightly shorter shift between the 21 and 19, tending to slip over to the 18 tooth sprocket unless careful.

    notably I've had this mech for about twice as long as any other. The tension adjust bolts and pulleys have gone out of shape or sheared insode half the time on otehr mechs, and I'm riding about 150 miles a week, so longevity is pretty impressive. Even at the price (in the Uk perhaps more competitive than campy, but still not a snip) it's well worth everyu penny.

    Strengths:    Super smooth shifts

    Weaknesses:    none

    Bottom Line:   
    This is the best upgrade I've done. Find it on sale or used and BUY IT. THere's no comparison to 105. If you get a new bike w/105, immediately take the rear der off and sell it on eBay to help offset the cost. You should get about $20 for it, maybe more. Even if it's used, you can still get a minimum of $10. D/A rear der's can be found on sale for no more than $65.

    Strengths:    Does the job. Pose value.

    Weaknesses:    Price but worth it if you want the best

    Bottom Line:   
    Never been convinced about the value of Dura Ace until I fitted the DA sti & rear mech to replace Ultegra. The internal cable routing of my KM40 can be 'demanding' on shifting but the DA copes fine and shifts are first rate.

    Strengths:    Smooth shifting, durability (I have at least 25,000 miles on mine), good looks, light weight.

    Weaknesses:    Well, I guess I could quibble about the price. But it's an excellent value compared to Campy, and if you look, you can find it for not (really) much more than Ultegra.

    Bottom Line:   
    I'm an ex-racer who does fast 50-100 mile road rides. So I appreciate quick, easy shifting and low maintainance as well as an attractive finish. The Dura-Ace 9-speed derailleur provides all of these qualities.
